For those unaware, there has been an issue with Steam recently regarding warnings being issued to various developers. The warnings are telling them that there games will be taken down from Steam if they do not remove pornographic content, their games would be removed from Steam, the biggest name that was hit being Hunie Pop.
A thing to note about these games being hit is that many of them have been up for a few years now, only to just now be hit by these warnings. There is also a tweet thread by developer Lupiesoft, talking about their takedown notice.

Various points brought up by Lupiesoft include that they are stricter then most other games about following Steams Guidelines, that everything in the Steam release of their game Mutiny! was cleared by steam after speaking with Mangagamer, the publishers who released Mutiny!, and that many western games that have not been hit at all have more explicit content then games getting hit by these notices.
There are a lot of rumblings going on about what may be the cause of this. Potentially laws going around that would affect platforms with both adult and non-adult content, bias against Japanese games from people who work at Valve, a potential group of people who may be mass flagging these games, and even talks of pressure from Paypal being involved. Right now nothing about why this is happening is entirely clear, but a lot of developers of Visual Novels and games with more lewd and adult content are feeling uneasy right now.
The answer is what do you do about it? A lot of people are saying to put pressure on Steam, but there is a problem with this being the major focus. The first is this is not the first time something like this has happened to this style of game. Visual Novels have always had a bit of a rocky relationship on Steam, so I don't imagine if after all this time applying more pressure to them will work, something a lot of people have to accept is this is not a massive market. Like Hunie Pop or not, the huge success of that game wasn't a sign of some shifting market, it was a surprise success of an indie genre that likely is never going to hit any kind of Mainstream market. If all these games disappeared from Steam, they likely aren't going to care all that much, it's not a big Market compared to their other ones.
There has been talk about building a new platform to sell these kind of games on, a place where more lewd and adult VN and other Anime Style games can get their releases. I don't know any of the names that have been talking about it, indeed many are just random twitter users, but this would probably be the best way to go about this.
With Valve having always been iffy on these things, and no real incentive to change to accommodate those developers, an alternative where they would be welcome is a must. I don't know if anyone will step up to do it, but I hope it happens. I may not be a big fan of Visual Novels or Puzzle games like Hunnie Pop, nor a fan of explicitly sexual games in general (I like fan service and sexual content fine, just not when those are the overall focus), but these games deserve to find their audience.
